Analysis and Characterization of Various Current Mirror Topologiesin 90 nm Technology

Abstract

Although large electronic systems can be constructed almost entirely with digital techniques, many systems still have analog components and current mirror is the core structure for almost all analog and mixed mode circuits. It determines the performance of analog structures, which largely depends on their characteristics. In this paper, we have analyzed various topologies of current mirror using 90 nm technology in Mentor Graphics and compared them based on different parameters like power dissipation, minimum output voltage, bandwidth, transfer characteristics etc.
